RESEARCH ON THE GRAFTING AFFINITY OF VARIETY FOR WHITE WINES ′VRANCEA′ ON ROOTSTOCKS WITH DROUGHT RESISTANCE

Abstract

Climate changes have considerably influenced the evolution of the thermal and water regime annually and during the growing season in the viticultural ecosystem of the Odobești vineyard. The use of drought-resistant rootstocks for grafting is one of the solutions to counteract this extreme phenomenon, which is increasingly present in the wine-growing areas of southern Moldova. The present paper presents preliminary results regarding the grafting affinity of the ʹVranceaʹ white wine grape variety created at RDSVO Odobești, on three rootstocks with drought tolerance obtained in the Romanian viticultural research (Drăgășani 70). M.′, ′Crăciunel 71 Bl.′, ′Ruggeri 140 Vl.′). The rootstock ′Berlandieri x Riparia Sel.Oppenheim 4 –4 Bl.′, was taken into the study as a control. The obtained results show a good and very good grafting affinity of the Vrancea variety on the ′Ruggeri 140 Vl.′ rootstock
